Trusting a company to be truly secure is, unfortunately, a terrible idea. They exist in a world where they can be compelled to cooperate or be shut down. They'll make the choice that continues to make some money.

Also any claim of no logging may as well be marketing nonsense. There's no way to verify it, logs have to be kept to some extent atleast for a little while to allow functionality, and adversaries may compel or compromise and thus create logs.
